Summary
-
1.
For the first time the reactions of polydialkylsiloxanes with Iotsich complexes of different structures were investigated, and on the basis of the results a method was developed for the synthesis of acetylenic and enynic silanols, which form new classes of oxygen-containing organosilicon compounds.
-
2.
Two possible ways are suggested for the formation of silanols in the reaction of polydialkyl(or aryl)siloxanes with organomagnesium compounds.
-
3.
A study is made of the reactions of acetylenic and enynic silanols with thionyl chloride and with vinyl ethers, of their dehydration, and also of the tendency of enynic silanols and their derivatives to polymerize,
-
4.
It is shown that enynic mixed di- and tri-siloxanes and their organic analogs (enynic alkenyloxy silanes) may be synthesized by the reaction of chlorosilanes with enynic siloxymagnesium bromides and enynic alkoxymagnesium bromides, respectively.
